By The Associated Press CHICAGO (AP) - Inhaler drugs used by millions of people with emphysema and bronchitis might slightly raise the risk for heart attacks and even death, a study suggests.The results aren't conclusive, and inhalers provide significant relief for these patients struggling to breathe. But the study authors urged doctors to closely monitor patients who use the inhalers.Most affected patients have both emphysema and chronic bronchitis. The condition's formal name, chronic...

A bronchodilator drug used for more than a decade by patients with chronic obstructive pulmonary disease is linked to cardiac risk, U.S. researchers said. The drug, ipratropium, is sold under the brand names Atrovent and Combivent -- the latter a combination product that contains ipratropium, researchers at Northwestern University's Feinberg School of Medicine said. The study, published in the Annals of Internal Medicine, found veterans with recently diagnosed COPD using ipratropium were...

Research shows how insects use trapped oxygen to breathe underwater Hundreds of insect species spend much of their time underwater, where food may be more plentiful. MIT mathematicians have now figured out exactly how those insects breathe underwater. By virtue of their rough, water-repellent coat, when submerged these insects trap a thin layer of air on their bodies. These bubbles not only serve as a finite oxygen store, but also allow the insects to absorb oxygen from the surrounding...

By Gillissen, Adrian To the Editor: I read with interest the article by Dr. Wedzicha and colleagues (1) wherein the authors compared clinical efficacy of a 104-week treatment with salmeterol/fluticasone propionate fixed combination (SFC) with a treatment with tiotropium bromide in chronic obstructive pulmonary disease (COPD). However, a few important aspects regarding the severity of COPD in the recruited patients and the interpretation of the results merit further attention. First, the...

By Livermore, Nicole Butler, Jane E; Sharpe, Louise; McBain, Rachel A; Gandevia, Simon C; McKenzie, David K Rationale: Panic attacks are common in chronic obstructive pulmonary disease (COPD), and the prevalence of panic disorder is at least 10 times higher than in the general population. In the current study, we examined resistive load perception in patients with COPD with and without panic attacks. Objectives: We tested competing hypotheses, based on conflicting results of earlier...

Cystic Fibrosis
2013-07-19 15:03:45

Cystic fibrosis, also called mucoviscidosis, is an autosomal recessive genetic disorder of the viscous secretions in the body. In turn, it effects the lungs, pancreas, liver, and intestines, as well as all other exocrine glands in the body. The most common genetic mutation that causes CF is a deletion of three nucleotides that results in a loss of phenylalanine, an amino acid at the 508th position on the protein. It should be noted, however, that there are over a thousand other mutations that...

Pharynx

The pharynx is situated directly after the mouth and nose and lies right before the esophagus. Formation and Orientation The pharynx is divided into three separate sections. The nasopharynx is the first part of the pharynx that lies between the soft palate and the base of the skull. The pharyngeal tonsils are located on the back wall of the nasopharynx. This portion of the pharynx is connected to the middle easr by the Eustachian tubes. The nasopharynx is linked to the nasal cavities...

Trachea

The trachea, commonly called the windpipe, is the air passage-way from the mouth to the lungs. Non-fish vertebrae all have a trachea. The moist with mucus walls of the tube-like structure trap inhaled particles to keep them from entering the lungs. Structure The trachea is an open-ended cylindrical structure that starts at the larynx and ends at the bifurcation. It is about one inch in diameter and can run four to six inches in length. Within the pipe there are anywhere from 15 to 20...

Lung

The lung is a vital organ that is a part of the respiratory system. Generally a person has two lungs; however, the body can function with only one. The lung’s main function is to move oxygen and carbon dioxide into and out of the bloodstream through gas exchange. The lungs are located lateral to the heart in the thoracic cavity. Each lung has a tip called the apex, which is superior in the body. The bases of the lungs rest on the diaphragm. They appear to be spongy due to their bundles of...
